Report Features
The report highlights any data that exceeds an alert value for the given flow technology. Alerting must be enabled for the given technology for the highlighting to be visible. Scroll horizontally to find a dark red highlighted cell, which indicates the specific attribute causing the alert condition. The reports list can be filtered using the filter box above the tree view. Reports will be filtered by the report name. After a report is selected, the report’s configuration options appear in the header of the report. There are several configuration options common to all reports (Device, Interfaces, time range, etc.), but some reports will have additional options.
• Source: There are two drop-down lists to select the desired device and interface. The first drop-down can go from All Devices to an Individual Device. In between the two dropdown lists is a … labeled button. Click to display a device pick list with an alphanumeric entry for searching the list. For more details on the device pick list, please see the Device Pick List section in the QoS reports. If an individual device is selected, then the interface dropdown will select either All Interfaces, or list the interfaces specific to that device. If All Devices is chosen, then the interface dropdown choice is All Interfaces. All devices, past and current, will appear in the device drop-down.
• Tags and Filters: Filter your flow report by typing in your defined Labels, Site, Tags or WAN designation. These reports will use all devices; a dialog box will alert you that these designations require the Source field to be All Devices.
• Filter: Dropdown list of common filters and any user-defined filters.
• Filter Icon: Brings up the Flow Display Filters Setup to create user-defined filters. • Direction: Choose among Inbound, Outbound or Inbound and Outbound. • Graph: Choose between Aggregation and Time-Series. Choose from Bytes, Bit Rate, Bytes, Packets or Packet Rate. For Top Analysis chart, choose among Basic Flow, Medianet, Application (AVC), NSEL, PfR, Wireless and Unknown flow types.
• Utilize Long-Term Cache: This forces the graph to use the long-term 15-minute data store for generating a report. Typically, the software will determine which store to use, the raw or long-term depending on the number of days, but in some cases with devices with large number of flow. In some cases, where there are a lot of flows from a device, it is more efficient to force the reporting to leverage the long-term store and this option allows the user to override the default behavior.
• Display Options: There are three options for displaying the top analysis data in time.
• – Time Sorted: Unique Flows: Displays unique flows in time from the oldest to the most recent. Uniqueness is determined by the following fields: Protocol, Source IP Address, Source Port, Destination IP
• – Address, Destination Port, Type of Service, Input Interface, Output Interface, First Switched, RTP SSRC, direction. Unique Flows is the default selection.
• Time Sorted: Raw Flows: Displays all flows in time from the oldest to the most recent.
• Byte Sorted: merge active flows and sort by highest byte count to lowest byte count for up to 5,000 flows. The Sorted paging option is available for Flow Types: Basic Flow and Medianet.
• Historical time period: Choose among 15m (15 minutes), 1h (one hour), 6h (six hours), 1d (one day), 1w (one week), 30d (thirty days) or Custom. When choosing custom, select the desired Start and End Date and Time.
• Est. non-filtered flows: Shows an estimate of the number of flows for the selected time range, device, interface and direction. Estimates give an approximate idea of the amount of data to expect.
• Execute Report: Click on the Execute Report button to create the Flow Report.
• CSV File Results: Click on the check box and click on Execute Report to send the full set of flow data in the table to the LiveNX server using a CSV format. A confirmation dialog box will appear to load the LiveNX server web page. Click on the OK button to proceed. On the LiveNX Server web page, right-click on the Right click to save CSV file link and then select Save target as… to save the report to a CSV file.
